It can be used, for example, as a TCP relay (one-shot or daemon),
as an external socksifier, as a shell interface to Unix sockets,
as an IPv6 relay, as a netcat and rinetd replacement, to redirect
TCP-oriented programs to a serial line, or to establish a relatively
secure environment (su and chroot) for running client or server shell
scripts inside network connections. Socat supports sctp as of 1.7.0.
